Yes you can, there is no compulsion that you have to continue with the field that you pursue then, you can choose whichever field you want for masters. But if the fields are not connected, the only drawback is that you will have to study the field from the basics, which is uncomfortable for a few people. But if you are passionate, you can do whatever you want. All the best! No field is ever referred to as "best field", it all depends on you.
For taking admission in M.Sc. in Forensic Science, the students should have completed bachelor's in science or relevant fields like pharmacy, engineering, criminology, and forensic science with around 50 percent and above aggregate in the undergraduation.
There is a lot of scope in Forensic Sciences. It is always required in investigations and solving cases. One can get employed in forensic labs, criminal investigation agencies, private agencies, government agencies, banks, detective offices, etc. You can become a crime laboratory analyst, crime scene examiner, forensic engineer, psychological profiler, computer analyst and many more.
If you're passionate about this field and you feel like you can make a career in solving crimes using your knowledge of forensic sciences, you should definitely go for it.
